N-hydroxysuccinimide esters undergo specific side reactions when exposed to competing nucleophiles.
the verdict
SUPPORTED
the evidence backs this
confidence 79/100
N-hydroxysuccinimide (NHS) esters are well-known to undergo specific side reactions and competing nucleophilic attacks (such as O-derivatization or ring opening) alongside their primary reactions.
